Chelsea boss Maurizio Sarri is hopeful that Toni Rudiger's injury isn't serious suffered in defeat at Liverpool.

Rudiger was forced off before halftime due to a knee setback.

Sarri said, "I hope it is nothing serious of course.

"But at the moment I am not able to say anything, we need to go to Cobham and have another visit with the doctor, and probably we will need something else tomorrow morning to be sure the injury is not serious.

"I am not sure."
